Description
Hornady Custom .223 Remington 55-grain FMJBT is built for range shooters who want factory quality without the hassle of rolling their own. Each round gets hand inspected before it leaves the plant, so you're getting the consistency you'd expect from a handload but with the convenience of factory ammo.
What Makes Hornady Custom .223 FMJBT Stand Out
The full metal jacket boat tail design is there for a reason. The boat tail helps the round fly straight and true downrange, while the FMJ construction means clean, reliable feeding in everything from AR-15s to bolt guns to Mini-14s. With a muzzle velocity of 3240 fps and 1282 ft-lbs of energy, these rounds produce consistent ballistics shot after shot. The brass cases are reloadable if you're into that, and the non-corrosive primers and clean-burning powders mean less cleanup at the end of a range day.
Built for the Range and Training
This is not hunting ammo, and that's fine because it's really good at what it is. The 55-grain bullet weight is the standard .223 load, and it's been proven reliable for target work and training. Whether you're working on your fundamentals with a new rifle or putting in volume at the range, this ammo will run. The consistency between shots makes it easier to diagnose actual rifle performance versus ammo-related fliers.
Why Reloadable Brass Matters
These rounds come in Hornady brass, which means you get a second life out of them if you reload. That's part of the value with Custom line ammunition. The primer pockets are crimped for reliability in semi-auto rifles, and the overall build quality is what you'd expect from a company that's been making ammunition since 1949.

Frequently Asked Questions
Can I shoot Hornady Custom .223 Rem 55gr FMJBT in my 5.56 NATO rifle?
Yes. The .223 Remington round is safe to fire in 5.56 NATO chambers, and these rounds are specifically loaded to .223 specification. Because of the tighter pressure curve of .223, you'll get reliable, consistent performance. Just make sure your rifle is actually chambered in 5.56 NATO first if you want to be extra careful.
Are these rounds good for hunting?
The full metal jacket design makes these better suited for target shooting and training rather than hunting. FMJ rounds overpenetrate and don't expand, which isn't ideal for game. If you're looking for Hornady ammunition for hunting, their Custom line also comes in soft point loads that are better designed for that purpose.
Why does this ammo say it's hand-inspected?
Every round of Hornady Custom ammunition gets a hand inspection before packaging to catch any defects or inconsistencies. This is part of what sets the Custom line apart from other factory ammo. It gives you the quality control you'd expect from handloaded ammunition but with the convenience of buying it off the shelf.
Can I reload these brass cases?
Yes, the brass cases are reloadable. The primer pockets are crimped for reliability in semi-auto rifles, which means you'll need a small base die or dedicated small base reloading setup if you're using an AR-15. After you fire them, they can be processed, trimmed, and reloaded just like any other quality brass.
